Avoid Non-Machinable Items
Some mailpieces require additional postage because their shape or size makes it dicult for the USPS to process with
mail sorting machines. These hard-to-process mailpieces, also known as non-machinable items, cost you more than
standard size mailpieces. Here’s what to avoid:
• Square envelopes
• Envelopes that are not exible
• Shipments with uneven thickness (for example, an envelope containing a pen)
• Envelopes with a clasp or string closure device
